Janet Yellen is both a professor in the
Economics department and at The Haas Business School. She served
as Chair of the Presidentís Council of Economic Advisors from 1997 until
1999 and served on the Board of Governors of the Federal Reserve System
from 1994 until 1997. She states that her research interests are
unemployment and labor markets, monetary and fiscal policies and international
trade and investment policy.

Yellenís main focus of research for the
greater portion of her career has been unemployment. Her motivation
for this subject stems from her desire to understand what appropriate policies
might look like and because unemployment is a puzzle and problem.
Since markets clear, unwanted unemployment should not happen, yet this
unemployment persists.

Since Washington, she has not yet fully
returned to doing the kinds of research she was working on before her work
there. Therefore, most of her recent research involves looking at
topics she focused on in Washington, such as sustainable employment.
This research looks at what went right in the 1990ís to answer questions
about how to achieve sustainable employment through policies today.
She and Alan Blinder have co-authored a short book that was recently published
as a response to a project that Solow and Kruger ran about sustainable
employment. This short book looks at the conduct of monetary and
fiscal policy and how each contributed to good economic performance.
They wanted to determine what part of the good times could be attributed
to good policy, and what part was attributed to good luck. They disentangled
these by looking in part at supply shocks of productivity and the decline
in benefits costs for firms.

Professor Yellen thinks that a good question
must be phrased as a question. A good question can have an answer
but that without a question it becomes difficult to begin research.
She thinks this question can come from the world around you and the things
you observe everyday. And she feels that seeing how your views might
apply in the real world, or researching to find out if your views have
merit bring about good questions and research. Also, when others
review and critique your work, often your find new avenues to explore.

For example, Yellen (and her husband)
thought that the legalization of abortion would be an excellent anti-poverty
measure. They asked the question, would legal abortion be a way of
alleviating poverty as giving women a tool to get rid of unwanted pregnancy?
They then noticed that around the time of legalization, out of wedlock
pregnancy grew. From looking at the world around them they found
the legalization of abortions led to a chain of events that made poorer
women worse off than before.

Yellen also suggests that data can come
from many places. These may include traditional sources as well as
those outside government sites. Often one can learn something from
reading first hand accounts from sociologists and data that is anecdotal
can be helpful. She also suggests using field research or surveys,
and that often finding how others have found their data on the topic youíre
interested in leads to new sources of data for you
